The cylindrical portion D is tapped at E to receivethe screw-.thread on the conical part D', and the body portion D istapped at Fto receive the screw-thread G on the cylindrical outer shellI-I. The shell H fits over the part D, and is provided Iwith theconicall end H', of refractory material, which is'connected to the shellHin the manner shown in jects slightly beyond the conical portion H. vIhave dscribedthe part D and the part H as connected to thepart D andshell H by 5o means of screw-threads.

I material 'and continued forward to form the parts 'D' and I-I.

The shell II is bored in such a' manner that a scmicircular duct C isprovided between' it and the part D and continued in `an upwarddirection through the conical end II of the burner to form an hpen ,ingin the shape' of a section of a ring, as

shown in Figs. 2 and 4. I is a two-way valve portion A. and duct C.

J is a duct, which communicates with the located in theibody duct B andwith the duct C when the valve' I has its position at ninety degreesfrom that shown in the drawings, which maybe accomplished by means ofthe handle K,the object arrangement is to divert the air orsteam'normally passing through the duct .I and B, for. the purpose ofmay have gathered therein. v

Referring to Fig. 5, L represents al standard, such as I employ forsupporting my i'mproved nozzle4 when the same is used in. connectionwith a metallurgical furnace.

In practice thest-andard is placed in such a position as, regards vthefurnace that the end of the nozzle shall be from three to'four inchesfrom the port-opening of the furnace.

The standard L is provided with the two supports M, which carry thespindle N.V The.A spindle N is arranged to have a vertical nio-Y 'tionand also to turn in the supports-M for ,tho

purpose of 'carryingthe nozzle or burner bin Yahorizontally-circulardirection fromt liodv of the furnace when not inuseQvQT,

plish these motions,;I provide the stiutli'iig`-l boxes O and O in thesupports M.

' .To effect the vertical movement of the spin'f' dleN, I providethe'wheel P, upon which iS'v the pinion R, which latter gears with thecular rack S .on vthe spind1e T representsl a Apipe communicating withlthe reservoir containing the liquid fuel, which it is desired to usewith the apparatus. T is asimilar pipe communicating with a supply ofsteam or air. U and U are valves which respectively control these twopipes.

'The' spindle shown at V, the upper of which communicates with thepipeWand the duct B of the burner or nozzle A,and'thelowerof which communi- Nis provided with ducts,a's

roo

cates with the pipe W and the ducts C and C of the nozzle A.

Y and Y. are valves, which respectively control the supply of oil andsteam or air to 5 the nozzle. l l

' I carrying niy im proved invention into ef- -inay use any of thehydrocarbon oils'or their. products-such=' as petroleum, naphtha,

or anyof the residuums derived from the disrq tillation of petroleum.These oils are deliv-i y eredto the burner through the vipes T YV andduct B. Through `the pipes T VWfand ducts l`C and C', I may supply steamor air. If steam is employed, it should have a pressure of 'at l5 -leastseventy,(70) pounds to the square inch but, preferably, should besuperheated sof vto prevent condensation.

4 ln place of using steam,particularly whe hi'gh temperatures aredesired,.I may use com 39 pressed air of from eighttoten poundspressnrc.

The valves Y and Y' are employed in my device'for the purpose ofregulating the lsupply of iliquid'fuel and steam or air, as desired.

' 25 In practice I- have found the best'results vfrom my'improved burnerwhen the liquid fuel is of uniform consistency and-allowed to tlow4through the nozzle by its own weight, y aided by thev injector action oftheenteri'ng '3o-steam or compressed air.

Ihave described myv improved burner as iliade up'4 of several"A pieces.This arrangement is simply for convenience of con uc tion,'as it will beevident to any mechanic 3'5" that the device can be made in a singlepiece.

By the arrangement of ducts in myinjector I obtain' 'a solid column ofliquid fuel and ay fan-shaped body of air or steam under the 'f columnof liquid fuel, the result of which is "46' tojproduce a broad stream ofdiffused fuel,

which burns, when the supply o f the two materials is properlyregulated,v without smoke,l

and thereby produces the bestresults obtain- Y ablewith burners of thisdescription.

' claim- 1. Ahydrocarbon-burnercomprisinga body under thedischarge-opening of the fuel-duct,` substantially as described.

2. A hydrocarbon-burner comprising a body portion having acentrally-located fuel-duct and an independent steamer air duct, thedischarge-opening of which is located below in sliape is a section of aring', substantially as described. l

3. A hydrocarbon-burner having independent ducts for fuel and steam orair, said steam or air ducts including the fuel-duct, and provided witha discharge-opening located under and behind the discharge-opening ofthe nel-duct, substantially as described. 4.Ahydrocarbon-burnercomprisiugabody ortion provided with a conical endand havng a centrally-located fuel-duct and au inlosing shell provided.with a conical end hav-` inga steam @or air duct, the discharge-openingof which is located below and behind the discharge-opening of thefuel-dnctand in a vertically-adj ustable and horizon tally-rotatabletubular spindle carried thereby, means consisting of a vrack of thespindle for adjustvalves for controlling the suppl'yof fuel and steamor-air tosaid burner, arranged as and in the manner set forth.4
